Patent CA-2517558-A1 (CA)
Title: Vibratory shaver
Inventor: PAAS EDWARD L
IPC: B26B21/38
Filed: 2004-03-04
Abstract: Vibratory shavers (10) are provided having a battery powered DC motor (42), which when energized rotates a weight (44) eccentrically mounted to a motor shaft (56). The rotating weight (44) imparts vibratory motion in the shaver housing (18) and thereby a razor cartridge (12) attached to the head of the shaver (10). The housing (18) is specially designed so that the shaver head will move more front to back than side to side. This can be achieved (a) with the shaver housing (18) having a wider aspect than a front to back aspect; (b) by thickening the side walls of the neck (36) of the shaver relative to the front and back walls of the neck (36); and (c) by appropriately positioning and designing braces of varied thicknesses. The housing (18) of the shaver (10) may be permanently sealed and provided with a battery (46) that may be recharged via induction. Alternatively, a cap (23) can be provided to provide access to a replaceable battery (46).

Title: Cyclone dust-collecting device and vacuum cleaner having the same
Inventor: OH JANG-KEUN
IPC: A47L9/16
Filed: 2006-03-14
Abstract: A vacuum cleaner includes a suction port assembly, a motor generating a suction force at the suction port assembly, and a cyclone dust collecting device for centrifugally separating air drawn in through the suction port assembly and the motor in sequence. The cyclone dust-collecting device includes an air discharge port penetratingly formed on an outer circumference of the cyclone dust-collecting device and exposed to an outside of the cleaner body, for guiding the air discharged to the outside. Accordingly, since the air discharge port is disposed in the cyclone dust collecting device, not in the cleaner body, a discharge channel for connecting the cyclone dust collecting device and cleaner body is omitted and thus a structure of the vacuum cleaner becomes simplified.

Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer readable medium, mechanisms, and means for merging indications of matching items of multiple groups and possibly associated with skip conditions to identify winning entries of particular use for implementing access control lists. Indications are received typically from an associative memory bank indicating which locations were matched during a lookup operation. Each of the entries is typically associated with one or more hierarchical groups and a skip or no skip condition. The matching entries are merged to identify one or more wining entries, these being matching entries not in a group that is skipped. A group is typically skipped if the highest priority matching entry of the particular group is associated with a skip condition. A priority encoder can be used to identify a single highest priority winning entry from the winning entries.
